PINION-HOUSING.

Specification of Letters Patent.

Patented Apr. 1d, 1914.

Application filed October 27, 1913. Serial No. 797,377.

To all whom it may concern Be it known that I, JOHN M. KELLER, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Pinion-Housings, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present improvements, relating as in dicated to a pinion housing, have regard more particularly to the provision of a suitable support for the spindles of pinions such as are used in driving rolling mills of various kinds. Such driving pinions are usually housed in a frame, or structure, apart from the rolling mill structure proper, their spindles being connected with the rolls through the medium of other spindles connected with said pinion-spindles by clutches or like means. It will be understood, of course, that my improved housing construction is not limited necessarily to the supporting of spindles in this particular relation, nor are the spindles necessary pinionspindles.

The object of the invention is to provide a support or housing of the character described, which will secure such spindles rigidly in desired spatial relationship and at the same time permit of the ready assembling and disassembling of the structure.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but several of the various mechanical forms in which the principle of the invention may be used.

In said annexed drawings:Figure 1 is a part end elevation and part transverse vertical section of a housing embodying my present improvements; Fig. 2 is a part front elevation and part longitudinal vertical section of the same; Fig. 3 is a top plan view of such housing; and Fig. 4 is a sectional v1ew corresponding to Fig. 1, but illustratmg a modification in construction. The particular type of housing illustrated 1n the foregoing figures of the drawings is a housing of the kind previously referred to as designed for use in connection with a rolling mill for the transmission of power to the several rolls of such a mill. To this end the spindles 1 which are supported in the housing of present interest, will be suitably connected with the roll spindles of such mill, and means (not shown) will be pro vided for driving one or the other of said spindles 1. The latter carry intermeshing pinions 2, preferably formed integrally with the spindles, whereby rotative movement of one spindle is communicated to the other.

The ends of the respective spindles are journaled in suitable bearings 3 which may be either bronze bushings or ordinary babbitted bearings, these bearings being in turn supported in plates 4 of disk-like outline secured in the respective side walls of the housing or frame 5, proper. To this end, such side walls are formed with circular openings 6 into which the disks 4 are adapted to snugly fit. In order to assemble the parts the housing is constructed in two sections divided on a single horizontal plane 7 so that when the upper section is removed the disks may be readily set in place or removed, as desired. By means of bolts 9, passing through the two sections of the housing, the latter may be drawn together so as to securely clamp the disks a in the circular openings 6. In practice, the surfaces of the housing sections are planed off so as to not quite contact with each other when the parts are thus assembled, whereby a proper clamping action upon the disks is applied, when the nuts are drawn tight on the bolts 9. The disks and the openings, in which they are held, are furthermore formed at a suitable point with flattened faces 11 and 12 which interengage so as to insure the proper location of the disks in the openings and prevent rotation of said disks. I11 order that the spindles 1 with their respective supporting bearings 3 may be readily separated when the upper housing section is removed, the disks 4 are likewise constructed in two sections separated by a single, diametral plane 13. Preferable such plane will be alined with the plane of division 7, which separates the housing sections, al though this is not necessary, and such disksections may be separated on a plane other than diametral and inclining at any angle to the horizontal. Where, as shown in Figs. 1 to 3 inclusive, but two spindles are supported in the housing, the bearings for the latter will ordinarily be vertically alined, one being thus sup ported in each of the two sections of the disks. In case, however, it is desired to support three spindles in my improved housing, the arrangement shown in Fig. 4 may be adopted, the bearing 3 for one of the spindles lying between the two disk sections and to one side of a central vertical plane, while the bearings for the two main spindles are moved somewhat to the opposite side of such central vertical plane. The bolts 9 are furthermore preferably so disposed that they pass through the sections comprising the respective disks 4: as well as through the housing sections. Thus all the parts of the frame are very rigidly secured together.

A ho-usingconstructed as just described, has been found admirably suited to the severe conditions of service encountered in rolling mills and the like. By reason of the extent of the contacting surfaces between the disks and the housing sections, any tendency on the part of the disks to rotate is materially decreased, and in any event, the bearings are held securely in desired fixed relation, by virtue of their being mounted in such disk sections.

Other modes of applying the principle of my invention maybe employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention i 1.
